PROCESS OF TREATING WOOL HATS.

Specification of Letters Patent.

Patented May 27, 1919.

Application led November 21, 1918. Serial N o. 263,534.

To all whom it may concern:

Be it known that I, GEORGE W. BOLLMAN, a citizen of the United States, residing at Adamstown, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Processes of Treating Wool Hats, of which the following is a specification.

This invention relates to improvements 1n the process of making wool hats, and the object in the present invention is to provide a new process whereby a wool hat will be made proof against distortion while under the ordinary adverse conditions of wear, such as weather conditions.

Heretofore, wool hats when finished, would retain their shape and appearance only while not exposed to wet or unfavorable weather, and it is my obj ect in the present instance to provide a wool hat that will withstand all of the ordinary weather conditions in much the same manner and to the same degree as the fur felt hat is supposed to withstand.

The invention consists of a series of steps forming a process, through which the hats are passed, and which will be fully described in the following specication.

The drawing forming a part of this application, shows, in central sectional view, a simple form of device whereby my invention may be carried out.

The hat bodies are blocked or shaped and are kthen pounced and buffed as usual.

These blocked hats are then nested or stacked, in graduated form according to size, as designated by the letter A, and they are then placed, while so nested, between two metal forms 1 similar in contour to the blocks over which they were originally shaped; they are then subjected to pressure, preferably by means of clamps 2, one only of which is shown in position, and, while still under pressure, they are subjected to a they are then ready to be removed from the f form and re-blocked to their final desired shape and nished as usual.

The result, when this process is followed as set forth above, will be a product not heretofore known, that is, a wool hat, not chemically treated, that is capable of retaining its shape and finish under the same adverse conditions as would a fine fur felt hat.,a

Having thus fully set forth my invention, and the mode of carrying it to successful operation, I claim and desire to secure by Letters Patent zl. The process of treating wool hats which consists in subjecting the hats, after being blocked, to a baking action, while held between two metal forms.

2. The process of treating wool hats which consists in subjecting the hats, while on the shaping blocks, to a baking action in a dry heat, then to a like baking action in a moist heat and then allowing them to cool while still on the blocks.

3. The process of treating wool hats which consists in blocking the hats, nesting a num` ber of the blocked hats, securing the nested blocks between two metal forms, subjecting the hats while so held to a baking action in a dry heat, then to a like baking action in a moist heat and then allowing the hats to cool. Y

4. The process of treating wool hats which consists of blocking and nesting a plurality of hats, incasing them between two metal forms, and then subjecting them to a baking action -in a dry heat, followed by a like action in a moist heat.

In testimony whereof I affix my signature.

GEO. W. BOLLMAN.
